INAIC maintains a list of known and
active registries for existing, resolving
TLDs that are open for SLD registrations.
Some TLDs are registered with special
charters or may not actually have
public registries. Most corporate
TLDs are not open for domain registrations.
Examples of such TLDs are .KIA, .SAAB.
Many Corporate TLDs are registered
for the sole purposes of providing
Intranet or Enterprise services over
own, unique, private namespaces.
To see if a TLD exists, and view
its registrant contact data, simply
enter the name of the TLD in the search
window of the INAIC home page.
To check if a publicly available registration
center exists, simply click the registry
link in the Global TLD Whois.
